I have a pretty bad flex pipe leak on my 20th. Would this leak cause a very rough idle almost stalling when I come to a complete stop. The Idle fluctuates from almost stalling to 1000rpms.
View 1 RepliesI have a 05 gli I just put a k04 turbo on. It runs on stock ecu but I have been told that's not the problem. When I start the car the rpm's spike to around 3 grand then slowly drop to normal idle rpm's when it gets under 1000 rpms the car starts to shake and idle hard. Idk what it is Cel is on and read misfires in 3 of 4 cylinders but checked plugs and everything they r fine. I'm thinking maybe vacuum leak or something along those lines.
View 6 RepliesJust checking in to see where you'd recommend to start looking for a rough idle issue. It seems to get worse once the car fully warms up. I took a vid, and although it may not seem horrible in the video, it sometimes causes throttle lag from a stop and causes the car to get close to stalling when falling from high RPM's. Take a look at the video .....

I've gone to 3 mechanics now and no one can seem to figure out whats wrong with my car. Here's whats happening:
About 1 1/2 years ago I took my car to get an oil change at Jiffy Lube (Yeah never again). When I left, my car was idling funny... Silly me didn't take it right back and have them tell me what was wrong.. so I let it go, well about a month later it started idling even weirder. Basically it feels like my car is shaking when it gets under 1000 RPM and I notice my RPM dial start falling and bouncing back, acting like its going to stall, but never does. I notice a loss of power when this is happening (on speed up and just accelerating in general). All of this is random, I can't seem to put a pattern to it as to when it happens. One day I'll start it up and everything is perfect... Then I'll shut it off and restart it later, and it starts vibrating and puttering again... No signals as to if its hot/cold or wet/dry, no environmental variables seem to cause it to happen anymore than others. And there is no check engine light on, everything "looks" normal.
What I've had done to it so far is:
Air filter changed / reseated
3 oil changes (keep getting told it will work)
Throttle cleaned
Computer reset for idle sensor data rebuilding
Now I'm told that I need new engine mounts, and that could be the reason for the vibration. I'm thinking that the vibration caused the mounts to wear out, more so than the mounts being the cause. Mainly because I don't see how bad mounts could cause loss in power/bad idling.
What could be wrong?!? Really bugging me and don't want to keep throwing money at it for phantom solutions. Seems like mechanics I go to can't figure it out unless there is a check engine light on with some diagnosis code to tell them exactly whats wrong.
I have a 05 gli and when in idle the rpms go down really low then shoot back up. what could be the cause and how would i go about fixing this?
View 1 RepliesHave a jazz blue chipped tuned with giac.. It does this random times.. When I come to a red light on idle the rpms go up and down just a bet but never stalls. The car vibrates and the engine shakes a bit. Engine is stable when car is on and off. Idk if its motor mounts or what?
View 10 RepliesI am running the GIAC X+ 93 octane tune with a cold air intake and when i hit full boost it fluctuates from 20 to 15 through out the gear. i am guessing its because of my stock dv. im looking in buying the eurojet dv.
View 13 RepliesI have a 2005 Mazda 6. When it is cold - I start the vehicle & begin to drive. When I slow down and the RPMS get around 1000 - the car begins to run really rough & try to stall. If I put my foot on the gas - I can usually prevent it from stalling. The problem disappears once the car gets warm. The dealership recalibrated the PCM based on a Mazda Alert. However, it has not corrected the issue. Looking for thoughts on what could be causing this?
View 5 Replies!995 honda accord, 5 speed. Idle is fine until the engine warms up, then fluctuates between 1500 to 2500 rpms. The idle control valve was cleaned- no change. Valve was also replaced -also with no change. Put old valve back on. Computer was disconnected after cleaning and also after each valve change.Would the next step be to remove and clean the fast idle thermo sensor? Also how do you check the coolant lines coming in. Anything else I would need to check, clean or replace.
View 2 Replies2012 SEL... Experiencing High Idle (1000 rpms) when the AC is ON. When I power the AC system OFF... the idle comes down to 700-800rpms. Then I power the AC back ON and it stays for the rest of my trip. Restart the car, and it's back to 1000 rpms with the AC on.
View 2 RepliesMy 2001 BMW 325Ci has an occasional "surging" idle problem. When coming to a stop or at idle, the engine will rev between 500 and 1000 rpm's. Sometimes it will correct the problem and idle normally, or keeps surging until it eventually stalls. When restarted it works fine. Tried fuel injector treatment, fuel stabilizer treatment, and replaced thermostat. Still surges about 50% of the time. Had it to a dealer, and computer says its running fine.
View 1 RepliesMy mother has a '04 Santa Fe 3.5. Her automobile makes a rattling/grinding sound when around 1000rpms/idle. However, the sound disappears when accelerating and drives like a charm. The sound returns once again around 1000rmps at idle or stop. I have changed the oil pan, replaced oil and filter and even put in a new battery. I'm not an aficionado when it comes to Hyundais (Subaru driver here).Car also has 180k miles.
View 6 RepliesI have a 2003 Ford Musang 3.8L v6 when I start my car for the first time of the day or after several hours of sitting the car idles high between 1000-1300 RPMs for approximately 15-20 seconds after that it idles down to 600-800 rpms. I changed the spark plugs wires air filter not sure what else it could be no Check engine light.
View 1 RepliesMy car is a 2001 honda accord v6. It sat for 3 winter months. When I go to turn it on in the morning, the car will rev while idling. Jumping between 1000 and 3000 rpms. Why this might be happening?
View 3 RepliesWell, it's looking sort of depressing for my '06 Sonata! I had an oil change done yesterday and now I'm getting a Low Oil Pressure Light on idle under 1,000 rpm's. Today the check engine light came on and it's code P0021.
I also experience very noisy "bearing" type noise upon start-up which happens for about 10 seconds or so. This has been going on for a month or so.
During my online research it's appearing that I may be suffering from the dreaded Timing Chain Tensioner I've read a lot about.
I'm aware of the TSB (10-EM-006) and have a copy of it if needed.
My question is this...my Sonata has 151,000 miles on it, well beyond the 100k warranty period. Will Hyundai repair my issue as a warranty item under that TSB?
I have several problems with my 06 FEH maybe some of you had same issues. I have imported this car from new york in my country 1 month ago, this is first Ford for me. Love this car but there is some issues and want to figure them out.
1. seat heating is turning on without clicking on the button, but not always it's random. Often on passenger seat some time on driver side to. I try to disable fuse but it also for 4x4 so it's not an option.
2. My engine idle RPMs is always higher that 1000. Maybe it is normal but want to be sure.
3. car cannot climb the hills here is the video.... car is just doing nothing to climb no rev up no trying just stall in middle. In my country there is some roads with hills like this and I want to visit that places.
4. Cruise control is working random to maybe it will start speed control in one click or after 20 -s try.
5.Is there any way to see soc? factory unis is replaced in my car with aftermarket radio. I have elm327 and tourque pro but can't find that option.
6. When monitoring with obd water temperature is always lower then it was on my other cars. its around 158-176F on other cars it was 200F.

This has been happening intermittently for a while now. The car has about 97k on it and I within the last 1000 miles have replace the timing belt, water pump, coolant temp sensor, tensioners, thermostat, and MAF (OEM BOSCH from ECS).
The car was overheating; all the cooling/timing related stuff was changed, no issues for a few weeks. Then it started misfiring and stalling like a madman in cyls 2 and 3. Ran ran if for the code pulled the MAF and sure enough it looks like the PO never cleaned it as there were probably 2mm of buildup on it; as preventative maintenance I went ahead and just replaced it completely.
Now, less than a week after I replaced the MAF the car will make random little popping noises under hard acceleration, and randomly will just completely stall; without showing the battery or check engine lights, similar to how it was stalling right before the MAF went bad. I live three miles from my office and it has happened going to and from every day for the past two weeks.
As far as I know the car is mostly stock (I purchased in in March). However it does have a knockoff BPV of some sort that I think could be causing the issue as the popping noise sounds like its coming from the passenger side of the car. What this might be (if it's not the BPV).
2010 F150 ... So I have the tick noise at rpm's 800-1000 at drive through, stops, etc. So I did research on it a few months ago and saw that it might be VCT's but should be able to drive. so I drove it waiting to save money and have it go to a shop. well this past weekend while coming home from work my oil light came on the pressure dropped to zero, I was on the highway so I drove about another mile to get off highway and once I got off my truck died. I had it towed to my house and I thought I blew my motor. So I started doing research here and found that the VCT's AND cam Phaser could be bad. so I replaced my VCT on driver side put it all back together it started and loud knock was gone. then after 5 mins it was back very loud knock!
So I shut it down and took apart the passenger side once I got the valve cover off I found the problem.... The bolt that holds the cam phaser in place snapped off and was riding along the camshaft. So I took that out and extracted remaining part of bolt. inspected my camshaft and it was really messed up. so I bought new Phaser and Camshaft. the camshaft just came in today and I am trying to put it back in. but the hole for the pin in the phaser doesn't line up and I cant spin the shaft to make it line up. should I spin the cam phaser? I marked the chain and the phaser is where it should be on chain, but with that bolt snapping off could that have thrown the timing off so my mark is no good? when I lay the camshaft in place it sits perfect and if I just move the phase over 2-3 links it will all fit together. Should I do that?
So my 20th AE has been wrecked. But here is the issue, the car will idle for a about 30 seconds to a minute but surge from 1500 rpms to around 750. But after that, it won't idle. If I let it sit for a couple of days, then it will idle for a little bit then die again.
View 2 RepliesSo about a week ago i got on the onramp to get on the freeway and stepped on the throttle as usual to get up to speed, but now for some odd reason the rpm's dont go past 5,500. Not sure whats wrong. I stay on the throttle but it pretty much stops and levels out at right around 5,500.. i must say i am pretty clueless. i just past 80k not long ago, and everything seemed to be going fine.
View 3 RepliesI bought my gti about a month ago and every time I warm it up in the morning or any time it has been sitting over a long period of time the rpms sit at about 1300 until about a minute and it goes under 1k ... I am not to familiar with this issue.
